Full Release Notes

1.128 - 2025-04-01

Highlights include:

- Added support for loading iTwin data using share keys as an alternative to user-based OAuth. When using a share key, set `ITwinPlatform.defaultShareKey`. [#12530](https://github.com/CesiumGS/cesium/pull/12530)
- Added `Frozen.EMPTY_OBJECT` and `Frozen.EMPTY_ARRAY` for use as default parameter values that avoid unnecessary memory allocations. [#12507](https://github.com/CesiumGS/cesium/pull/12507)
- Fixed entity tracking for delayed datasource bounding spheres. [#12465](https://github.com/CesiumGS/cesium/issues/12465)
- `Camera.getPickRay` now correctly returns a ray with origin in world coordinates in orthographic mode. [#12500](https://github.com/CesiumGS/cesium/pull/12500)
- Fixed camera zooming in 3D orthographic mode when pixelRatio is not 1. [#12487](https://github.com/CesiumGS/cesium/pull/12487)
- Fixed shape bounds and transforms for cylinder-shaped voxels. [#12522](https://github.com/CesiumGS/cesium/pull/12522)
- Fixed an issue where clamped entities' height updates could stall when using high-resolution terrain due to a growing queue of tiles in `updateHeights` in `QuadtreePrimitive`. [#12476](https://github.com/CesiumGS/cesium/issues/12476)
